Idle revving

Ford fiesta 2010 1.6 zetec S is constantly revving by itself in neautral and occasionally drops so low that it stalls out. Took it to garage and they couldnt find anything wrong with it, no leaks or mechanical failures, they ran a smoke test and nothing came back. Any ideas/thoughts ?
